本文实例讲述了PHP计算整个MysqL数据库大小的方法。分享给大家供大家参考。具体如下：
这里用MB，KB或者GB的格式返回计算结果。
rush:PHP;">
function CalcFullDatabaseSize($database,$db) {
$tables = MysqL_list_tables($database,$db);
if (!$tables) { return -1; }
$table_count = MysqL_num_rows($tables);
$size = 0;
for ($i=0; $i < $table_count; $i++) {
$tname = mysql_tablename($tables,$i);
$r = mysql_query("SHOW TABLE STATUS FROM ".$database." LIKE '".$tname."'");
$data = mysql_fetch_array($r);
$size += ($data['Index_length'] + $data['Data_length']);
};
$units = array(' B',' KB',' MB',' GB',' TB');
for ($i = 0; $size > 1024; $i++) { $size /= 1024; }
return round($size,2).$units[$i];
}
/*
** Example:
*/
// open MysqL connection:
$handle = MysqL_connect('localhost','user','password');
if (!$handle) { die('Connection Failed!'); }
// get the size of all tables in this database:
print CalcFullDatabaseSize('customer1234',$handle);
// --> returns something like: 484.2 KB
// close connection:
MysqL_close($handle);
希望本文所述对大家的PHP程序设计有所帮助。
